well the brand and model im not exactly sure, its like MegaBook and some number after, ill check and post once im able to.
To be more exact about the HD ,it does a couple of clicks not really loud , then you just can hear the sound of hd .
Also i saw in another post that holding the power in 1-5 mins would reset the bios , without batteries or plugged on the wall, it didnt work , still same dead screen,

BTW if the bios were fried , how did it boot before when the bios got reset?
